Months of hard work and sacrifice have paid off for the Richmond Rovers side who were crowned champions at the Auckland Rugby League under-20 grand final.Richmond trounced Papakura 32-18 at Cornwall Park on Sunday allowing them to finish their impressive season at the top of the table.Coach Luisa Avaiki says the newly crowned champions are ecstatic with the win.It was a slow start for the central Auckland side, with Papakura coming out firing to take the first two tries.But as soon as Richmond had their first points on the board the winners' medals were as good as theirs, Avaiki says."They have worked really hard for this and have sacrificed a lot since we started pre-season training in November last year."We set ourselves some goals and we've reached them."This is the first time in more than four years the Grey Lynn club has been able to enter a team at this level of the competition.Many of the players competed with last year's under-18s side and will now be looking to move further up the ranks next year.
